Let's denote the amount saved in the first year as a d 24,000
1) Amount saved in the 1st year:a
2) Amount saved in the 2nd year:a + d
3) Amount saved in the 3rd year:a + 2d
From the given information, we have the total amount saved in 3 years:
a + (a + d) + (a + 2d) = 24,000
Simplify the equation:
3a + 3d = 24,000
Divide by 3:
a + d = 8,000
Since the amount saved in the 1st year is more than the 2nd year, we have:
a > a + d
Simplify this inequality:
a > 8,000
Therefore, the person's savings for the 3 years area + (a+d) + (a+2d) = 2a + 3d = a + a + 8,000 = 2a + 8,000 8,000
\textbf{Answer:} The person's savings for 3 years are2a + 8,000 a > 8,000
